You can copy a cab setup from one preset to another; besides the cab and speakers, this operation also copies all the mic positions. Nice. However, this does not copy the mixer settings. I can't find a way to copy mixer settings - right-clicking on the mixer icon in the chain view, or right-clicking anywhere in the mixer view proper, does nothing. It would be super useful to be able to copy mixer settings along with cab and mic setup; in my mind (and to my ears) they are all one bundle of related parameters.
Am I missing something? Is there a way to copy mixer settings between presets?
